DESCRIPTIONS
The S1C17704 is a 16-bit MCU that features high-speed operation, low power consumption, small size, large address space,
and on-chip ICE. The S1C17704 consists of an S1C17 CPU Core, a 64K-byte Flash memory, a 4K-byte RAM, serial
interface modules (UART that supports high bit rate and IrDA 1.0, SPI and I2C) for connecting various sensor modules, 8-bit
timers, 16-bit timers, a PWM & capture timer, a clock timer, a stopwatch timer, a watchdog timer, 28 GPIO ports, an LCD
driver with 56-segment × 32-common outputs and a voltage booster, a supply voltage detector, 32 kHz (typ.) and 8.2 MHz
(max.) oscillators, and a voltage regulator for generating the 1.8 V internal voltage. The S1C17704 is capable of high-speed
operation (8.2 MHz) with low operating voltage (1.8 V). Its 16-bit RISC processor executes one instruction in 1 clock cycles.
The S1C17704 also provides an on-chip ICE function that allows on-board erasing/programming of the embedded Flash
memory, on-board debugging and evaluating the program by connecting the S1C17704 to the ICD Mini (S5U1C17001H) with
only three wires. The S1C17704 is suitable for battery driven applications with sensor interfaces and up to 56 × 32-dot LCD
display, such as remote controllers and sports watches.
The product lineup offers two S1C17704 models with a different main oscillator.
